Replying to [comment:18 jdemeyer]:
> David, in principle I agree with your changes. However, the gcc report
indicates a problem with gcc/tree-ssa-loop-ivopts.c and because of this it
suffices to disable -fivopts. New spkg which does this (and also
simplifies the gcc version check):

I think my test
{{{
if [ "x`$SAGE_LOCAL/bin/testcc.sh $CC`" = xGCC ] && [ "x`$CC
-dumpversion`" = x4.6.0 ] ; then
}}}
for the version is preferable. I can't see the point in calling a C
compiler with --version then greping the output, where there is a
documented option (-dumpversion) to show just the version,
Also, this could well fail for another compiler with a version of 4.6.0 -
I think its safer to test for gcc first.
